11. Any evidence of severe or uncontrolled systemic disease (e.g., unstable or uncompensated respiratory, cardiac, hepatic, or renal disease).
12. Alanine amino transferase (ALT) or aspartate amino transferase (AST) greater than 2.5 times the ULRR if no demonstrable liver metastases or greater than 5 times the ULRR in the presence of liver metastases.
13. Evidence of any other significant clinical disorder or laboratory finding that makes it undesirable for the patient to participate in the trial.
14. Uncontrolled seizure disorder, active neurological disease, or greater than Grade 2 neuropathy.
15. Keratoconjunctivitis sicca or incompletely treated eye infection.
16. Abnormal marrow function as defined as absolute neutrophil count \<1,500/ul or platelets \<100,000/ul.
